Question

describe the structure of human ear ? how perception of sound takes place in human being

Answer 1

The ear is an advanced and very sensitive organ of the human body. The ear’s function is to transmit and transduce sound to the brain through the parts of the ear: the outer ear, the middle ear and the inner ear.

The major task of the ear is to detect, transmit and transduce sound. Another very important function of the ear is to maintain our sense of balance.

The sound waves travel from the outer ear and in through the auditory canal, causing the eardrum, or tympanic membrane, to vibrate. This, in turn, causes the three small bones, known as the ossicles, or the hammer, the anvil and the stirrup, in the middle ear to move. The vibrations move via the oval window through the fluid in the cochlea in the inner ear, stimulating thousands of tiny hair cells. This results in the transformation of the vibrations into electrical impulses finally perceived by the brain as sound.

The ear consists of many small parts, but can be divided into three major parts:

The outer ear
The middle ear
The inner ear
